A waste storage tank that is closed and converted to product storage is no longer subject to Parts 264 Subpart J/265 Subpart J. A containment structure used to contain a release during an immediate response to a spill is exempt from permitting and the technical standards if the hazardous residue is removed. A release may be subject to section 3004(u) corrective action. Inactive disposal units that are clean closed before 11/19/80 may be subject to sections 3004(u) or 3008(h) corrective action if other hazardous waste management units are currently in operation.
